Problems solved by technology

During the drilling process, the high-speed operation of the motor will cause the entire rock bolter to vibrate and shift, which will easily cause the drill rod of the pneumatic rock bolter to deviate and cannot be positioned and drilled.
In addition, the existing pneumatic rock bolt rigs generally can only drill vertical holes, inclined holes or horizontal holes, which makes the rig single-function and limited use scenarios

Abstract

The invention discloses a pneumatic anchor rod drilling machine operation positioning device and method for geotechnical engineering. The device comprises a square base and a square seat, wherein a top surface of the square base is provided with a supporting platform, a first electric push rod, a first shear type lifting platform and a second electric push rod; the first shear type lifting platform is connected with a positioning plate which is provided with a positioning hole; the square base is provided with a first circular groove; a top end of the first electric push rod is provided with alimiting plate, and the top end of the second electric push rod is provided with a first supporting plate which is in contact with the limiting plate; the limiting plate is provided with a pluralityof limiting holes; the square seat is fixedly arranged on a second shear type lifting platform; the square seat is connected with a second supporting plate which is provided with a second circular groove; the other side of the square seat is fixedly provided with a third electric push rod, and the top end of the third electric push rod is hinged with a third supporting plate through a spherical hinge; and a fourth electric push rod and a fifth electric push rod are hinged on two sides of the square seat through spherical hinges.

Description

Technical field [0001] The invention relates to a device for fixing a bolt drill, in particular to a working positioning device and a positioning method of a pneumatic bolt drill used in geotechnical engineering. Background technique [0002] When drilling bolt holes in existing pneumatic bolting rigs, it is common to place the pneumatic bolting rig under the surrounding rock that needs to drill the bolt hole. The operator adjusts the pneumatic bolting rig's power through the control button on the operating rod. The air leg is raised to make contact with the surrounding rock, and then the drill pipe is activated for drilling and bolting operations. During the drilling process, the high-speed operation of the motor will cause the entire bolter to vibrate and deviate, which will easily cause the pneumatic bolter's drill rod to deviate and unable to perform positioning and drilling. In addition, the existing pneumatic bolting rigs generally can only drill vertical holes, inclined h...
